Zero is ideal black and 100 is ideal white. This value suggests a mid-dark color on an sRGB display.

ABOUT THIS REFERENCE
Pantone 655 U on screen.
Pantone 655 U is shown here as the sRGB simulation #4E5D7F. The suffix U identifies the uncoated graphics reference. Its nearest generic process conversion is C39 M27 Y0 K50.
These values help with mockups, UI handoff, and color discovery. They do not reproduce the spectral behavior of a physical spot ink, and the CMYK recipe is not an official separation.
Before production: verify the color in a current physical Pantone publication, use licensed digital data where required, and approve a proof on the intended material.
READING THE COLOR
Mid-dark, moderately muted,
and digitally approximate.
The derived CIELAB coordinates put Pantone 655 U at L* 39.55, a* 3.39, and b* -20.92. In plain language, this screen simulation is mid-dark, moderately muted, and cooler, with a blue direction. Its calculated chroma is approximately 21. These descriptions help compare the digital reference with neighboring colors; they are not names assigned by Pantone.
A positive value indicates a red direction.
A negative value indicates a blue direction.
HEX, RGB, CMYK, and LAB serve different jobs
#4E5D7F is the compact HEX form of the RGB values 78, 93, 127. Both describe the same sRGB screen simulation and are appropriate for web comps, interface tokens, presentations, and other emitted-light previews. They do not encode the spectral data or ink formulation of a physical Pantone standard.
The displayed CMYK value—C39 M27 Y0 K50—is calculated from that sRGB simulation without an ICC output profile. Real process separations depend on press condition, paper, ink, black generation, and total ink limit. The LAB value is derived from sRGB under standard assumptions and is useful for comparisons inside this site; do not substitute it for licensed measured data when a specification requires official values.
OTHER PAPER FINISHPantone 655 C#002554
Uncoated versus coated
The related coated reference is simulated as #002554. C and U are separate entries because paper finish changes the way ink color is perceived. Do not remove the suffix or assume the two versions share identical production values.

- Keep the full reference.Write Pantone 655 U, including the U suffix, in the brief and artwork notes.
- Use #4E5D7F for previews.Apply the HEX or RGB simulation when a browser or screen mockup needs an approximate visual.
- Decide spot or process.Ask whether the job will use a dedicated spot ink or reproduce the appearance through process inks.
- Set the production condition.Confirm the stock, coating, print method, color profile, and viewing light with the supplier.
- Approve physical output.Compare a current official standard and an appropriate proof or production sample before sign-off.
Frequently asked questions
What is the HEX approximation for Pantone 655 U?
The independent sRGB simulation used on this page is #4E5D7F. It is intended for screen previews and is not an official Pantone production specification.
What RGB values approximate Pantone 655 U?
This reference uses RGB 78, 93, 127 in the sRGB color space.
Can I print Pantone 655 U with CMYK 39, 27, 0, 50?
Those CMYK percentages are a generic, profile-free estimate derived from the screen value. Ask the printer for the correct separation or specify the verified spot ink.
What does the U suffix mean?
U identifies the uncoated paper version in the Pantone graphics system. Keep the suffix when communicating the reference.
